How to add 90 days from create date into another date field

[Stacy1]

I need to add 90 days to the date that a record is created and put it in another date field.

Any thoughts on how I do that.  I am trying it with an onsubmit script because it needs to be done when the record is created.

Thanks,

Stacy

You can create a business rule and use addDays function to add 90 days
